The tutorial so far has been just fine. I am having trouble, however, keeping the player from walking off of the window even though I have given him the behaviour bound to layout, bound to edge. Another issue I am having is that even though I set the player at every tick set angle toward(mouse.x,mouse.Y) my mouse does nothing to the player unless I left click at which point he fires a bullet. The mouse, however, will not move the player at all.
Your best bet at a resolution is to post your .cap. This will allow others to see what you have done and hopefully determine what the problem is in your project.
Obviously, this being the - now retired Construct Classic section - there will be far fewer users who visit and so help may not be as quick.
